Used as a key intermediate in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in the development of COX-2 inhibitors. Its structure allows for selective modification to enhance pharmacological activity and reduce side effects. Commonly employed in medicinal chemistry for optimizing drug candidates targeting inflammation and pain. Also utilized in research settings to develop novel isoxazole-based bioactive molecules with potential antitumor, antimicrobial, or antiviral properties.
